H. W. WHITE MATERIAL FOR BUILDING CONSTRUCTION Orfliaal Filed Feb. 20 1920 Reissued Nov, 18, 924.

To all whom it may concern:

Be it known that I, IIENRY W. WHITE, a citizen of the United States, and resident of New Orleans, parish of Orleans, and State .of Louisiana, have invented certain 'new and useful Improvements in Materials for Building Constructions, of which the following is a specification, and which are illustrated .in the accompanying drawings forming a part thereof.

The invention relates to buildings and has for an object the provision of a form of construction that shall be simple, durable, warm, cool, cheap and which may be constructed with a minimum of skilled labor. A further ob'ect of the invention is the provision of a orm of material that may be used in such construction.

' An illustrative embodiment of the invention is shown in the accompanying drawing in which Fig. 1 is a perspective view of a portion of abullding partially completed, and partly broken away to show, the construction, and

Fig. 2 is a detail longitudinal section of a piece of material embodying the improvement in building material.

A building constructed according to the present invention, as shown, comprises "as to Walls, merely the. studding or other frame members, and sheets of material, in the nature of artificial lumber, secured directly thereto and providing all necessary elements for warmth, weather resistance and outside structure may also provide the roof if desired but since the construction thereof will be obvious it is not considered necessary to illustrate the same. Q1

The material made according to the invention comprises, as a major element, a layer, as 10, of dry waste fibrous material such as straw, dried asses of any character, dry leaves, weed s or any other waste material that ma be available and which when treated as escribed, is capable of being formed into a layer of sponge-like nature. To provide the material of the invention the waste material is treated with a waterproofing substance which of causing the elements of the fibrous maerial to adhere to each other at their points f contact'without filling the inter-spaces he mass. i

finish of a pleasing appearance. The same is capable sssr AVAILABLE cow HENRY W. WHITE, 0]? NEW ORLEANS, LOUISIANA.

KATERIAL FOB BUILDING CONSTRUCTION.

The waterproofing material at present preferred for this purpose is asphalt of not too soft a composition. If such an asphalt be applied hot, or in fluid condition by reason of containing a'cut-back as benzol,

the individual fibers or elements of the waste material will be saturated thus rendering the material of these fibers or elements waterproof. To attain the result contemplated by the present invention this waterthe material is preferably compremed to a suflicient degree to cause the points of contact of the elements with each other to adhere,- but not 'suflicient to close the cells of the mass.

The compression of the cellular mass is preferably produced in the operation of applying surfacing layers to the mass. As shown, a back layer, as 11, is provided formed of .felt saturated with asphalt or other waterproofing material, fabric or paper which layer may be coated with an adhesive substance 12, preferably asphalt, of the same nature used in treatment of the fibrous layer 10, for the purpose of causing it to adhere to the cellular layer 10. While the backing layer 11 is preferably thoroughly waterproof yet this quality is not essential since it is not directlyexposed to the elements. v p As a facing for the cellular layer 10, there issliown a layer 13 preferably felt saturated wit 1 of asphalt 14 similar to layer 12 ap l thereto to cause adherence of the cel ular layer thereto. Preferably the layer 13 is faced by a. coating of asphalt 15 having grit, sand, shell, or other non-adhesive refractory material, as 16, embedded therein to conceal and protect asphalt and to provides. pleasing appearance.

Toenable the material described to serve asphalt and having a layer or coat 7.

without support other'than the frame members of the building, the material is so assembled asto be rigid and is formed into fiat sheets of a size convenient for handling.

Rigidity ofthe material is furnished by the.

layer 10 which, for this purpose, is made very inuch thicker than layer 11, or than combined layers 13, 14, 15. This is feasible because of its cheapness and of this layer secures the function of 'heat insulation due to its cellular nature in addition to rigidity. Thesheets of material formed as described owe some of their rigidity to an action of the parts of the nature of a truss action, since the surface layers act as tension members and the layer 10 as a body cross connected lattice work.

Having provided sheets of the nature described, a wall may bevery readily constructed. as shown, by erecting studding, as 17 so spaced thatthe edges ofthe sheets may i meet on oertain'of the studs, and the sheets may be nailed directly thereto. To make the joints weather proof andin'visible, the edges joint.

of the sheets may be coated with fluid asphalt and may be pressed together. The raw.

asphalt exposed at the joint may be conoealed'by taking loose material of the nature utilized for layer 16 and pressing it ainst the joint as by a trowel. The nail eads may be covered by asphalt and grit may be applied thereto at the same time as to the If preferred the joints by a batten 18wand "corner boards .19. When this practice is followed, half timbered effects may be readily secured by other pieces 20, -21, placed between the battens.

A building embodying the present inven-' tion may be constructed in a' minimum time with very little skilled labor, and will be 4 durable, warm in winter and cool in summer and its exterior may be given a pleasing appearance chosen from a wide variety of possibilities. I l i Minor changes may be made in the physical embodiment of the invention without debuildings comprising in combination a-layer parting from its-spirit. v v I claim as my invention: 1. A sheetmaterial for 'the .-exterior.of

of;waste'*ma terial, the individual elements of which are saturated and thinly coated with waterproofing material, said elements contact to-form a cellular mass, an a wateradhering to each other at their oints'of the thickening "and thinly coated with bituminous material,

" 3.-A sheet material for building con- -hering to' and closing the cells of said layer at one surface, a waterproof facing layer may be covered as proof facing layer adhering to said first,

named layer. 2. A-sheet material for the exterior of buidings comprising, in combination, a i

major layer of wastefibrous material, the individual elements of which are saturated said elements adhering at their points of contact in the mass to form a cellular mass,

a waterproof facing layer adhering to and closing the cells of said layer at one surface thereofand a backing layer of sheet material adhering to and closing the cells "of said layer at'the other surface.

struction comprising, in combination, a ma or layer of waste fibrous materlal having its individual elements thinly coated with asphalt and adheringat their points of contact' to providea rigidity-giving,heatinsulating cellular mass, a backing layer adadhering to and closing the cells of said layer at its other surface and a .layer of weather proof 'finishing material adhering" to said surface layer.

4c. The method of manufacturing sheathing boards for buildings,- whichcom rises forming a cellular layer'of loose nonelted fibrousmaterial, treating the same with an adhesive. compound for binding the fibres together, compressing to a sufiicient degree to cause the'points of contact of the fibres K out closing the cells, cementto adhere wit ing a facing,'includingan asphalt layer, to the face of said layer of fibrous material.

and imbedding a layer of grit in the exposed surface of said "asphalt layer.

5. A sheathing board for walls of build 'ings comprising, in combination, a ma or layer of non-felting fibrous material, the individual elements of, which are thinly coated and cementedto each other at their points of contact with adhesive water proofing material to form a rigidity-giving heatinsula'ting sponge-like body, anda layer of weather protective material secured to the face of said major layer.
